Students AI written blog fools most humans and rockets to the top of the charts

WHY THIS MATTERS IN BRIEF

As AI’s get better at generating and writing content, then writing viral content, soon most of the content we read could be AI generated rather than written by humans.

At the start of the week, Liam Porr had only just heard of OpenAI’s GPT-3, a powerful new Artificial Intelligence (AI) text generator whose predecessor GPT-2 was dubbed one of the most dangerous AI’s in the world for its ability to generate high quality fake, or synthetic text that could be used for both benign and nefarious purposes like large scale fake news generation, or as in one case, helping an anonymous US college student get top grades for his schoolwork. By the end of the week, the college student had used the AI model to produce an entirely fake blog under a fake name.

It was meant as a fun experiment. But then one of his posts reached the number-one spot on Hacker News. Few people noticed that his blog was completely AI-generated. Some even hit “Subscribe.”

While many have speculated about how GPT-3, the most powerful language-generating AI tool to date, could affect content production, this is one of the only known cases to illustrate the potential. What stood out most about the experience, says Porr, who studies computer science at the University of California, Berkeley: “It was super easy, actually, which was the scary part.”

GPT-3 is OpenAI’s latest and largest language AI model, which the San Francisco based research lab began drip-feeding out in mid July this year. In February of last year, OpenAI made headlines with GPT-2, an earlier version of the algorithm, which it announced it would withhold for fear it would be abused. The decision immediately sparked a backlash, as researchers accused the lab of pulling a stunt. By November, the lab had reversed position and released the model, saying it had detected “no strong evidence of misuse so far.”

The lab took a different approach with GPT-3; it neither withheld it nor granted public access. Instead, it gave the algorithm to select researchers who applied for a private beta, with the goal of gathering their feedback and commercialising the technology by the end of the year.

Porr submitted an application. He filled out a form with a simple questionnaire about his intended use. But he also didn’t wait around. After reaching out to several members of the Berkeley AI community, he quickly found a PhD student who already had access. Once the graduate student agreed to collaborate, Porr wrote a small script for him to run. It gave GPT-3 the headline and introduction for a blog post and had it spit out several completed versions. Porr’s first post (the one that charted on Hacker News), and every post after, was copy-and-pasted from one of the outputs with little to no editing.

“From the time that I thought of the idea and got in contact with the PhD student to me actually creating the blog and the first blog going viral – it took maybe a couple of hours,” he says.

The trick to generating content without the need for much editing was understanding GPT-3’s strengths and weaknesses.

“It’s quite good at making pretty language, and it’s not very good at being logical and rational,” says Porr. So he picked a popular blog category that doesn’t require rigorous logic: productivity and self-help.

From there, he wrote his headlines following a simple formula: he’d scroll around on Medium and Hacker News to see what was performing in those categories and put together something relatively similar. “Feeling unproductive? Maybe you should stop overthinking,” he wrote for one. “Boldness and creativity trumps intelligence,” he wrote for another. On a few occasions, the headlines didn’t work out. But as long as he stayed on the right topics, the process was easy.

After two weeks of nearly daily posts, he retired the project with one final, cryptic, self-written message. Titled “What I would do with GPT-3 if I had no ethics,” it described his process as a hypothetical. The same day, he also posted a more straightforward confession on his real blog.

Porr says he wanted to prove that GPT-3 could be passed off as a human writer. Indeed, despite the algorithm’s somewhat weird writing pattern and occasional errors, only three or four of the dozens of people who commented on his top post on Hacker News raised suspicions that it might have been generated by an algorithm. And all those comments were immediately downvoted by other community members.

For experts, this has long been the worry raised by such language-generating algorithms. Ever since OpenAI first announced GPT-2, people have speculated that it was vulnerable to abuse. In its own blog post, the lab focused on the AI tool’s potential to be weaponized as a mass producer of misinformation. Others have wondered whether it could be used to churn out spam posts full of relevant keywords to game Google.

Porr says his experiment also shows a more mundane but still troubling alternative: people could use the tool to generate a lot of clickbait content.

“It’s possible that there’s gonna just be a flood of mediocre blog content because now the barrier to entry is so easy,” he says. “I think the value of online content is going to be reduced a lot and we’re going to be flooded very soon with lots of shoddy content – even more than we are today.”

Porr now plans to do more experiments with GPT-3, but he’s still waiting to get access from OpenAI.

“It’s possible that they’re upset that I did this,” he says. “I mean, it’s a little silly.” But it also shows that when it comes to writing top ranking content AI’s is getting as good, if not better, than any human blogger – and unlike human bloggers, like me, it never sleeps and can just keep going, and going, and going, and going … well, you get the idea.
